DOUBLE-HUNG STEEL SASI-I.

Application filed. March 25, 1922. Serial/No. 546,816. ifl

To all whom t may concern.'

Be it known that I, MATHEW ZEMAN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, has invented certain new and useful Improvements in Double-Hung Steel Sashes, of which the following is a specifcation, reference being had to the accompanying drawings.

This invention relates to improvements in double hung steel sash, and an important object of the invention is to provide in a construction of this character sash and frames so constructed that all joints at points of contact are weather proof.

A further object of the invention is to provide in a construction of this character an improved construction of meeting rails for the sash which not only affords a weather tight joint but which permits the use of a cylinder lock or latch for securing the windows in closed position.

A still further object of the invention is to provide an improved engagement between the jamb rails and the jamb of the complete construction.'

A further and more specific object of the invention is to provide a novel and eilicient dividing rail joint which is weather proof and which may be readily assembled.

A still further object is to provide an improved sill construction for use with windows of this character.

Other objectsfand advantages of the in vention will bec-ome apparent throughout the course of the following description.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like partsy throughout Figure 1 is a vertical sectional view taken through a double hung steel sash and frame therefor constructed in accordance with my invention;

Figure 2 is an'elevation thereof;

Figure 3 is a section taken on the line 3-3 of Figure 1;

Figure 4 is a perspective view-showinga completed joint of the dividing rails;

Figure 5 is a side elevation of the continuous member of the dividing rails;

Figures 6 and 7 are detail views showing the manner of constructing the joint of the sections of the other of the dividing rails;

Figures 8 and 9 are detail sectional views showing the manner of mounting an ordinary latch upon the meeting rails.

Referring now more particularly to the drawings, lthe numeral 10 designates the frame, the numeral 11 the sill and the numeral 12 the frame head. In accordance with my invention, the frame 10 is divided into three separable sections, an outer section 13, the jamb portions 14 against which the sash operate, and an innersection 15. Each jamb portion 14 is provided in the outer edge thereof with a notch 16 and each inner portion of the frame is provided with a notch 17, these notches, when the frame sections are combined, providing grooves or slots, the purpose of which will presently appear. The metal at the edges of the slots 16 and 17 is turned outwardly from the sash opening, as indicated at 18 and .19, affording guides.

The frame head or lintel is composed of `a single section comprising a pair of horizontally disposed surfaces 20 and 21 connected by an integral vertical wall 24, the outermost section or surface 21 being vertically offset from the section 20. The section 21 is reverted, as indicated at 23, to form a downwardly opening channel 22. The offsetting of the head frame sections 20 and 21 permits reception of the upper end of the upper sash 25 which is outwardly ldisposed with respect to the lower sash 26.

Each of the sash 26 embodies jamb rails 27, these jamb rails being substantially similar. Each is provided at its outer face with an outstanding flange or runner 28 extendingl into a corresponding slot of the side frame, and aportion 29 flatly abutting the jamb portion 14.` The runners 28 of the jamb rails operate intermediate the guides 18er 1S) of their respective flanges andare provided with shoulders 30V abutting the outer ends of these guides. Each jamb rail further embodies an inwardlyl directed ange 31 against which'the glass may be disposed.

The upper sash member 25l is provided with a head rail 32 which, when the sash is in the uppermost position, abuts the vertically offset portion ofthe section 2O of the frame head affording a break draft, since incoming air must necessarily pass about the head rail and downwardly past the offset 24. The head rail 32 further embodies an upwardly directed flange formed upon its upper surface, as indicated at 33, which when the-sash1isin-its uppermostfposition projects into the-channelA 22 in the iframe head and is disposed intermediate the channel walls 33. To an edge Yportion of this flange 33 may be secureid'the chains or yflexible. elements 34 employed for connect-ing the sash with a counterbalance, not herein shown. The head rail-32 ifurtheri'embodies an inwardly or downwardly directed flange 35 against which 'glass may be disposed in glazing and which combines .with the flanges 31' ofthe j amb rail of the upper sash 25 for the reception ofthe glass.

The upper sash 25 is shown further Iprovided'with dividing rails36and 37 dividing thesash into a `plurality of apertures. The dividing rail 36 haslits upper `end suitably jointed as at 38,fto the Ihead rail and its lower endvjointed, as at -"39,1to lthe meeting rail 40 of the uppersash, the construction of which willbe hereinafter described. The dividing rails 36 and 37 arerea'ch substantially T-shape'd in cross section, the head 41 ofthe T affording vglazing flanges and the stem 42 thereof sub-dividing and spacing thepanes. Thestemk 42 ofthe vertical dividin'g rail 36 'has zformedi therein an opening F43. i A

The dividing rail 137, or'transverse dividing rail, is formed'in two separate sections, each section'ha-ving.itsouter 'end suitably jointed, as `at 44, "to afjamb'rail 27. The inner ends of the rail sections have-thehead portions 41 thereof undercut, as indicated at45,"to fit againstand lform al close joint withthe head ofthe vrail 36, the stem portions 42fof'these'sections Yprojecting to abut against the adjacent side of the stem 42of the /rail'36 and beingprovided `with an outstanding offsetllange `'4:6 in parallelrelation tothe stem-42 'thereoffandoffset fromthe stem a ldistance equal ttov approximately onehalf its thickness, the foffset of the flanges 46 ofthe sections being oppositely disposed sc'lthat when the sections are 'combined `:the stems 42 and fhead 41 'ithereof are aligned. In'assemblingthe dividing'rails 36 and 37, the sections of the'rail 37 are arranged upon opposite sides of'therail 36in their proper position kand the flanges '46 lvthereof `-forced into the opening 43 of the stem 42'of the section36 'whereby the vsections of the rail 37 'are aligned `and have ya joint with lthe rail 36, the securing Iport-ion of which is j. formed.

disposed interiorly of the flange .portions andinfwhich there =is "no direct draft line The.,meeting railsof the :sash-25 and 26 are substantially similarinconstruction and accordingly but 'one thereof is Vherein described. Each 'comprises 'a horizontal portion 147 provided v'at one side thereof `witha glazing flange 48 .against which the glass of its sash vis lto :be disposed, and at the 4remotefromits respective sash with a flange 51 which likewise has an ogee face, the flange 51-beingof suchvlength that the flange 50 will pass the similar flange of the other meeting rail and againstwhich the'flangc 51 abuts when the sash are in the closed position. Attention is directed tothe fact that by this construction the flange 49 of the respective meeting rails of the sash 25 and 261 are spaced, affording room tor a cylinder lock, designated at 52, although the same need not-necessarily beemployed, a latch being used if so desired. Each meeting rail is further provided withflanges 53 connectingthe ends-of the horizontal `portions '47 and the flanges 49 and having at its outer face an angular flange 54 projectinginto the corresponding slot of the side frame.

The sill '11 is formed of a'nnit-ary casting combining the ledge 55 and outer sill 56 sill rail of the Alower sash embodies a hori.

zontalportionl abutting Athe flattened top of the yridge 57, a vertically directed *glazing'ftange 62 vwhich is directed upwardly, and a downwardly directed vertical `flange 63 abutting Iagainst the outer 'face of the shoulder' portion 59 of the ridge 57, the lower end of this flange 63 fitting against the filleted portion-60 and against the ledge 55 providinga comparatively long tortuous connection between the sill and sill rail effectually breaking anytendenoy to draft. The sill rail is further `provided upon the face ofthe flange 63 with an foutstanding shoulder A64 against which the upper end portion 65 of the attaching rflange ofthe handle member 66 maybe disposed whereby totakethe strain of lifting the window from the fasteners 67 of the handle.

The glazing flanges of each ofthe sash rails-have formed therein in the face thereof against which thev glass is disposed, grooves 68 within which a packing medium 'may be disposed. If so desired, the glass may be held in vposition against the glazing flanges by means of angle braces 69 secured to the rails except in the case of the dividing rails, yin which yconstruction it is preferred that a U'-shape`d-member 70 straddlingthe stem 42 of the dividing 4rail and having feet 71 abutting against the vglass 72 be employed. The U-shaped member may be secured tothe stem -by securing elements 7 3 extending `through vthe ybody por- "opposite side thereof with .a vertically keX- tion thereof -and engaging 'in the ybase of the T stem of the rail. In the formation of the frame the central section 14 thereof is preferably made adjustable. In accomplishing this clamps Will be .provided Which will be bol-ted to the sections.

From the foregoing it is believed to be obvious that a double hung Window constructed in accordance With my invention is particularly vvell adapted for the purpose for which it is intended by reason of the fact that the same is substantially Weather proof throughout, and by reason of the fact that the construction thereof is of such a simple nature as to render the same inexpensive to manufacture and very durable in service. It will furthermore be obvious that the construction as hereinbefore set forth is capable of some change and modification Without materially departing from the spirit of my invention and I according ly do not limit myself thereto except as hereinafter claimed.

I claim:

1. A sash embodying dividing rails each substantially l'shaped in cross section and one of which is continuous and provided in the stem portion thereof With an opening, the other of said rails being formed in sections, the head portions of Which have a join-ted connection With the head of the continuous rail, the stems of said sections being provided with projecting portions extft tending into said opening and maintaining the head portions thereof in alignment.

2. A sash embodying dividing rails each substantially T-shaped in cross section and one of which is continuous and provided in the stem portion thereof with an opening, the other of said rails being formed in sections, the head portions thereof being undercut for the reception of the head portion of the continuous rail, the stems of said sections abutting the stem of the continuous rail and being provided with projecting flanges extending into the opening thereof and overlapping one another.

3. A sash embodying dividing rails each substantially T-shaped in cross section and one of which is continuous and provided in the stem portion thereof with an opening, the other of said rails being formed in sections, the head portions thereof being undercut for the reception of the head portion of the continuous rail, the stems of said sections abutting the stem of the continuous rail and being provided with projecting flanges extending into the opening thereof and overlapping one another, said flanges being each offset from its attached stem a dista-nce equal to approximately onehalf of its thickness.

In testimony whereof I hereunto aiiix my signature.

MATHEW ZEMAN.
